SQL语法中,用查询语句时,以下执行顺序正确的是?
A: from、where、groupby、select、distinct*、having、orderby
B: from、where、groupby、having、select、distinct*、orderby
C: from、groupby、where、select、distinct*、having、orderby
D: from、where、groupby、select、distinct*、orderby、having
A: from、where、groupby、select、distinct*、having、orderby
B: from、where、groupby、having、select、distinct*、orderby
C: from、groupby、where、select、distinct*、having、orderby
D: from、where、groupby、select、distinct*、orderby、having
举一反三
- 数据库执行SELECT查询语句时,各子句的书写先后顺序是:() A: HAVING,WHERE,GROUPBY B: GROUPBY,HAVING,WHERE C: WHERE,GROUPBY,HAVING D: WHERE,HAVING,GROUPBY
- SQL中属于分组查询的语句是() A: WHERE B: GROUPBY C: ORDERBY D: HAVING
- SELECT语句中只能与GROUPBY子句配合使用的子句是() A: ORDERBY B: HAVING C: WHERE D: INTO
- where子句、groupby子句、having子句在select语句中的顺序是() A: having子句、groupby子句、where子句 B: groupby子句、having子句、where子句 C: groupby子句、where子句、having子句 D: where子句、groupby子句、having子句
- 以下SQL子句的撰写顺序表达正确的是: A: SELECT、FROM、WHERE、GROUP BY、HAVING、ORDER BY B: SELECT、FROM、WHERE、HAVING、GROUP BY、ORDER BY C: SELECT、FROM、WHERE、ORDER BY、HAVING、GROUP BY D: SELECT、FROM、ORDER BY、WHERE、GROUP BY、HAVING
